Abstract The Research and Development Bureau at the B. Verkin Institute for Low Temperature Physics & Engineering, in a joint project with Orbita Ltd, USA, has created a flexible cryogenic refrigeration system for use in continuously operating equipment. The refrigeration system uses a thermoaccumulator in combination with an intermittently active Stirling cryocooler. The thermoaccumulator is a cryostat with an interior temperature of 64 K ± 0.5K maintained by the solidification of nitrogen. The cryocooler, a linear drive split Stirling design, periodically refreezes the liquid nitrogen. The temperature is controlled by a closed-loop control system included in the package. The system operates from a variety of power sources, including 110V, 60 Hz AC, 110V, 50 Hz AC, and 27 volts DC.
